The late merging phase of a galaxy cluster : XMM EPIC Observations of A3266
Jean-Luc Sauvageot, Elena Belsole, Gabriel W. Pratt
We present a mosaic of five XMM-Newton observations of the nearby () merging galaxy cluster Abell 3266. We use the spectro-imaging capabilities of \xmm to build precise (…
Structure and scaling of the entropy in nearby galaxy clusters
G. W. Pratt, M. Arnaud, E. Pointecouteau
Using XMM-Newton observations, we investigate the scaling and structural properties of the ICM entropy in a sample of 10 nearby (z < 0.2) relaxed galaxy clusters in the temperature…
Probing the dark matter profile of hot clusters and the M-T relation with XMM-Newton
E. Pointecouteau, M. Arnaud, G. W. Pratt
We present results based on XMM-Newton observations of a small sample of hot galaxy clusters. Making a full use of XMM-Newton's spectro-imaging capabilities, we have extracted the…
Further evidence for a merger in Abell 2218 from an XMM-Newton observation
G. W. Pratt, H. Boehringer, A. Finoguenov
(Abridged) The galaxy cluster Abell 2218, at z=0.171, is well-known for the discrepancy between mass estimates derived from X-ray and strong lensing analyses. With the present XMM…
The structural and scaling properties of nearby galaxy clusters: I - The universal mass profile
E. Pointecouteau, M. Arnaud, G. W. Pratt
We present the integrated mass profiles for a sample of ten nearby (z<=0.15), relaxed galaxy clusters, covering a temperature range of [2-9]keV, observed with XMM-Newton. The mass…
Merging clusters of galaxies observed with XMM-Newton
E. Belsole, J-L. Sauvageot, G. W. Pratt +1
We present results from the XMM-Newton observations of our ongoing program on merging clusters. To date three clusters have been observed, covering the temporal sequence from early…
